United's roster:
GK- De Gea top 5 in the world
RB- Valencia , solid , not starting United quality, imo
CB- Bailly, love the guy- looks like he's getting worse under Mourinho
CB- Lindelof, undecided
LB- Shaw, horrendously managed by Mourinho. Good player
CDM- Matic, really good player
CM- Pogba, really good player, potentially (likely) elite with a different manager
CM- Fred, I dunno
RW- Lingard, solid player
CF- Lukaku , not my cup of tea, but a really good player
LW- Sanchez, really overrated (imo), but still a good player vastly underperforming
----------------------
GK- Romero, one the better backups around
RB- Dalot, no idea.. seems promising
CB- Jones, good enough to be a 3CB , imo
CB- Smalling, good enough to be a 4CB, imo
CB- Rojo , why is he on the team?
LB- Young, no... just no
RB/LB- Darmian, never should've been signed by United. Isn't as bad as you think, though.
CM- Herrera, completely under-utilized and a shadow of his Bilbao days
CM- Pereira, looks quite promising, but being wrongfully deployed
CM- Felliani, why the hell is he on the team?
CM- McTominay, seems like a potential squad player for some time. Nothing special
CAM/RW- Mata, terribly utilized by Mourinho. Could start for a ton of quality sides in Europe and prosper.
LW- Martial, horrendous management by Mourinho. Just brutal. He's a potential star.
LW/CF- Rashford , extremely promising player, stagnating after the Sanchez deal. Looks like he's plateaued under Mourinho at 20 years old.
-------------------------------
CB/RB - Fosu-Mensah, should be playing for United
